Abstract (en)
The inertia components (1,2) have power transmission paths (3,H,6;3,4,L,5,6) between input and output shafts (7,8). The paths with distinct speed ratio has high and low clutches (H,L) with adjustable torque transmitting capacities. When the power is transmitted between components at constant speed ratio, the torque transmitting capacities are adjusted to be equal to input torque (Tin) of shaft (7). An independent claim is also included for vehicle drive line.
